HEATING SYSTEM.

To all whom it may concern:

Be it known that I, NORRIS M. FINLEY, a citizen of the .United "States, residing in Nor-ristown, Pennsylvania, have invented certain Improvements in Heating Systems, of which the following is a specification.

()ne object of my invention is to provide a system of radiators and piping therefor'so arranged that certain of said radiators may be-used with steam for heating purposes, while the remainder may be supplied with hot water resulting from the condensation of such steam it being also desired to provide automatically actin regulating means for causing discharge 0 water from the system .when its heating effect is less than is desired. 7

Another object of the invention is to so arrangethe radiators and piping of a heat ing system that all of the heat contained in a given body of steam shall be 'efiiciently utilized, part in steam radiators, and part 1n hot water radiators.

I further desire to provide a system, having the above noted characteristics, with automatic means governed by the temperature of the water of condensation, for governing the discharge of water from the radiators at a predetermined temperature, in connection with means whereby such apparatus may be set by hand so as tooperate underpredetermine-d conditions.

These objects I attain as hereinafter set forth, reference being had to the accompanying drawings, in Wl110l1-- Figure l, is a diagrammatic view illustrating the apparatus comprising my invention; Fig. 2,1s a side elevation, partly in sec-' tion, illustrating my inventionas applied to an indirect heating system, and Fig.3, is an enlarged side elevation illustrating, artly in vertical section, the automatic'regu ating means preferably employed by me.

Referring to the above drawings, a represents the inlet of a steam main A supplied with steam from any suitable source and having connected to it at intervals steam ra. diators a' -a.. In the present instance, these radiators are shown as connected in a single n them the water of condensation, provide drip pipes b, b, b ,connected at 1ntervals into the steam main A; the first entering said main between the radiators a, a the second between the radiators a and a, and the last connected directlywith 1 the pi e systemand for the purpose of carrym ofl froi --diato rs to each hot water radiator,

'beunderstood that Specification of Letters Patent. Patented- Dec. 21, 1909. Application filed April 29, 1907. Serial No. 370,782.

end of the steam main.- To each of these drip pipes I connect a hot water radiator 0 and these latter are in turn all connected to a water discharge pipe C, having an outlet at 0. Connected to the water main C at some suitable point I provide a tank 0 ha'v-- ing a gage glass 0 and. afloat 0* connected through a suitable series of levers and links to a stop valve 0 in the water main- Under operating conditions, steam is supplied to the system through the'main A and flows to the various radiators a, a a, which are arranged for direct heating in the ordinary manner, the water condensing-in said radiators in the present instance going back tothe steam main and thence through one or more pipes b, b, b to the hot water radiators 0; The valve 0 is so connected to the float cthat the water is discharged from the system whenever it rises to a predetermined level, so that instead of being discharged to the sewer or hot well while in a warm condition, it is retained. and utilized in the radiators. From. time to time, as the quantity of waterof condensation increases beyond some predetermined height, the float rises and opens the valve 0 thereby permitting a certain amount of the cold water,

which is naturally at the lowest part of the system, to bedischarged. As/soon, however, as the level of water has fallen sufiiciently in the fadiators c, the floatcloses the valve or allows said valve to close, depending on the adjustment of the weight on the rod f It will be seen that the amount of heat, by the hot water radiators a de-.

given ofi pends lar ely upon the level of the water in them, or the space above said water is filled with steam. should become advisable to have more heat delivered by the radiators 0 than couldbe' steam.

While I have shown but twosteam rait will in practice the sizeand number of steam radiators is proportioned .to the number of hot'water radiators con nectedQwith them,-so that thewa-ter of-condensation from a given bank of radiators If, for any. reason, it

water comingfrom the radiapartof the radiators a may be then filled with will be sutlicient to supply and properly operate the hot water radiator or radiators connected to it.

In practice, I find it convenient, though not absolutely necessary, to place the steam radiators in the upper floors of a building and the water radiators in the basement or lower floors, as by this means the arrangement of the piping is materially simplified.

Should it be. desired that water in the hot water radiators shall be discharged when its temperature reaches a certain point, I provide the device illustrated in Fig. 3, which, under operating condition, is connected to control the valve 0" and to operate either independently or in conjunction with a the float. For this purpose I mount within "the water main C any.convenient form of thermostat, which, in the present instance, consists of an iron tube 6 rigidly connected at one end to a plug e in the end of the. main and at the other end supported loosely within the said main. This second end has rig-- idly connected to it a brass rod 6 which extends through the plug a and is threaded into a tubular spindle 6 havin a handle a and so mounted as to be capa ble of being turned and longitudinally moved in a bear-* ing 6 mounted in a yoke piece 6 The longitudinal movement of this spindle in its bearing is limited by a collar as shown in Fig. 3. To opposite ends of this yoke piece are connected a pair of links f and f, while to a clamp f rigidly fastened to the pipe 0 in any suitable position are pivoted two other links f and f The free ends of the links f and f are pivoted together-=-and the end of the link f is pivoted to the link 1 a short distance from the end of the latter.

A fifth link f extends between this end and.

a variable point on an arm of the lever f. This latter is pivoted to the links f and f at their pointof junction and connected through link f to the lever f which is di-- O falls below a predetermined point, there will be a difierential change inthe length of the thermostat consisting of the tube e and the rod 6 resulting in a movement of said rod into the pipe. As a result, the yoke (2 will move toward the end of said ipe and cause such a rel'ative movement of t e levers f f, f and f as will movevdownw'ard the end of the lever f, which is connected to the link f; this movement being multiplied by the use of a connecting link As a consequence, the lever f is mov on its fulcrum f and opens the valve 0 thereby permitting the escape of water from the maln C until the steam has so far entered the hot water radiators as to raise the temperature of the water of condensation sufiiciently to cause an outward movement of the rod 6 of the thermostat. Under these conditions, the above operations are reversed and the valve 0 is closed under the action of the weight on the rod as well as of the weights of the various ro s, levers, etc., therebypermitting the hot water to agaln accumulate 1n the hot other at a number of points so as to'permitof their relative ad ustment, as-for example-the link or rod f may be attached to the lever} at any of a number of points. The rod to the float c" is adjustably con nected to the link (Z, while in addition the rod (1 is provided upon the valve casing 0*", having a number of holes whereby the lever 1" may be held by means of asuitable pin so thatit is fully open or closed; in which case there would be no substantial operation of the thermostat. If when the valve was thus held open there should be an action due to the thermostat which might injuriously affect the apparatus, the link f may be disconnected from the remainder of thelmechanism. It is to be noted that the float is normally free to control the valve in the casing 0 independently of the thermostat, for the parts are not only so adjusted that thisis possible, but it will be noted that the yoke piece e is free to move in one direction longitudinally of the thermostat in order to render this possible.

In Fig. 2, I- have shown my invention as applied to an indirect system otheatingand n tlns case a fan G for forcing a1r through the system is provided at its outlet with any desired number of steam radiators g and g supplied with steam from the main 9 The water of condensation from these is con ducted through a pipe g to a'hot water radiator g in which the water level may be maintainedat any desired point by means of such an arrangement of-part-s as is shown in Fig. 1. Under operative conditions, cold air is drawn by the'fan. over the hot water radiator g and after passing through said fan isforced around the steam radiators g and 'g', thence passing to the rooms to be heated. a

It is to be notedthat by means of my systerm, I utilize for heating purposes the hot waterotherwisewasted, employing this in water radiators forming'part of the system in which are included the steam radiators from which the condensed wateris supplied,

the float c preventing more than a predetermined accumulation of water within the radiators, and the thermostat causing the main, a series of steam radiators connected thereto, hot w ter radiators connected to receive water of condensation from said steam containing elements, means operated by the water andincluding a discharge valve for.

preventing rise of water in the system above a 'n'edetermmed height, and temperature controlled means arranged to also act on said valve for causing discharge of water from said water 'adiato1's,\v-hen the temperature has fallen to.-a predetermined point.
